Key result
Lone aortic valve commissure causes severe AS and aortopathy in a middle-aged man.
Why the study?
Aortic stenosis has diverse etiologies ranging from congenital to degenerative diseases, warranting description of rare morphological variants causing severe stenosis.
This case report highlights a distinct morphological feature of the aortic valve that can cause severe aortic stenosis and aortopathy.
Rare commissural morphology may explain atypical AS with aortopathy; leaves open prevalence and need for systematic validation.
The etiology of aortic stenosis can vary from congenital abnormalities of the aortic valve and acquired causes, such as rheumatic heart disease, to degenerative aortic valve disease. In this report, we describe a distinct morphological feature of the aortic valve causing severe stenosis with aortopathy in a middle-aged man.
